Renowned photographer Mary Ellen Mark’s (born in Philadelphia, 1940; died in New York, 2015) numerous honors and awards included a Fulbright Scholarship, Guggenheim Fellowship, Cornell Capa Award, and the 2014 Lifetime Achievement in Photography Award from George Eastman House. During her lifetime, her photo essays and portraits were exhibited worldwide and appeared in numerous publications, including Life, the New York Times Magazine, and the New Yorker. Her photo essay on runaway children in Seattle became the basis of the Academy Award–nominated film Streetwise, directed and photographed by her husband Martin Bell, and was published in book form in 1988. Mark published twenty-one books, including American Odyssey (Aperture, 1999), Twins (Aperture, 2003), Exposure (2005), Seen Behind the Scene (2009), Prom (2012), and Tiny: Streetwise Revisited (Aperture, 2015). In addition to producing her own work, Mark taught photography workshops for nearly thirty years; her thoughts on teaching are captured in one of her final titles, Mary Ellen Mark on the Portrait and the Moment (Aperture’s Photography Workshop Series, 2015).
